Patent DE-2908040-A1 (DE)
Title: Machine for cutting several strips of sweets or luxury food etc. - having knife blades mounted on wheels which immerse in wash water for lower part of its travel
IPC: B26D7/08
Filed: 1979-03-01
Abstract: Strips of material laid side by side are cut into uniform short lengths. The material is of a plastic, tacky nature esp. for the centres of block shaped food and luxury foods (such as 'dominoe pieces'). The process commences with a stepwise moving conveyor. This conveyor moves the strips forward to rotating knives in a series of steps so that the strips are uniformly cut into pieces. The Knives are mounted on wheels which rotate. The lower part of the wheels are immersed in a bath of water, which serves to clean the blades after each cut. Used for producing luxury foods etc. where fillings are made from sticky materials. The machine works reliably and reduces waste production to a minimum.

Title: Monitoring gas flow speed in mine ventilation systems - using acoustic source and receiver in flow and having whistle or microphone placed in duct
Inventor: DONATH HORST DR
IPC: G01P5/24
Filed: 1979-03-27
Abstract: The gas flow speed monitoring device is esp. for monitoring underground mine ventilation systems is simply produced and installed and ensures positive reliable monitoring. It eliminates the disadvantage of membrane switches that are easily influenced by external sources and can fail to indicate flow speeds below the minimum permissible for safety. It avoids the contamination and overheating problems of semiconducting thermoresistance types. An acoustic transmitter (1) is placed in a ventilation duct (2). An associated acoustic receiver drives an evaluation circuit (5) whose pulse output is dependent on the flow speed reaching one or one of several defined values. The acoustic source (1) may consist of a whistle or microphone placed in a duct carrying the monitored flow. An amplifier may be placed between the receiver and evaluation circuits.

The permanent magnets are relatively movable to one another and have opposite poles (3) facing one another. The relative movement of the magnets may comprise rotation of the poles (3) about an axis perpendicular to the direction of movement of the rail vehicle, or sliding of the poles (3) in this direction. In either case, the amount of displacement is less than the spacing between adjacent, opposing poles (3). Pref. the secondary part (1) is of Aluminium with eddy currents induced by relative movement of the facing magnets.

Title: Preset thermostat valve assembly - has control member with face working against seat in housing upstream of plug
IPC: G05D23/02
Filed: 1979-06-16
Abstract: The valve is esp. thermostatically-controlled. It is used on a heating radiator and is preset by a control member which is raised and lowered. Its plug, movable axially in relation to its seat, is shut in opposition to a return spring. The control member has a sealing face working against a seat in the housing upstream of the valve seat. Upstream of this face a thread on the member screws into one in the housing. The plug also has a thread in which one of the same length on the member engages during movement of the latter into the presetting position. A bar passing axially through the plug so engages with the member that it cannot turn in relation to it.

Title: Movable X=ray appts. - has carrier mounted above couch which may be tilted vertically for access of second tube
Inventor: SCHMETTOW DIETER DR ING
IPC: A61B6/00
Filed: 1979-08-13
Abstract: The X-ray tube is fitted beneath the patients couch, with a carrier which is mounted above the couch, the tube and carrier move on a common sliding carriage so that the latter is always correctly aligned with the X-ray beam. Sometimes an additional tube above the couch is used in which case the carrier must be moved out of the way. This is achieved with little effort by sliding the carrier (19) horizontally backward on rollers (26) along a guide rail (23) and then tilting it vertically along a vertical guide rail (29). There is little movement of the centre of gravity and therefore no counter weight is required.

Title: Closed circuit heating of roasting furnace which uses hot gases - involves use of heat exchanger with double circuit
Inventor: RAFF GERHARD DIPL ING
IPC: A23N12/08
Filed: 1979-10-11
Abstract: Roasting machine is described in which a hot gas is used to process the contents of the machine and in which the off gases are processed in an after-burner. The heat content of the off-gases leaving the after burner are utilised to preheat the incoming gas to the roasting machine. The after-burner has a main chamber from which hot gases are directed to one circuit of a heat exchanger from which they exit as cold off-gas for discharge into the atmosphere. The heat content passes to a second circuit in the heat exchanger from which heated fresh gas is withdrawn and used to process the contents of the roasting machine. The system avoids recycling the harmful or odorous constituents of the gas.

IPC: B30B9/24
Filed: 1980-09-13
Abstract: A belt filter press has upper and lower endless rotating support belts each inclinedly mounted on two large drums held in a frame and defining a gradually tapering gap along which a slurry is fed during de-watering between filter belts whose circulation paths include the pressure section between the support belts. In the earlier part of this section support rollers above and below the gap are offset from each other, applying broad area pressure. In the later part are one or more pairs of rollers whose axes above and below the gaps lie in a common plane perpendicular to the pressure section, so that the rollers apply substantially linear pressure. Lateral sealing of the gap is provided by inclined transverse rollers together the edges of support belts and filter belts. Used for general sewage or for slurries in the coal, ceramic, ore industries etc. The linear pressure rollers remove water more effectively in the later filtration stages.

Title: Placing U=clamps in scalp tissue - involves unit with clamp magazine and spring handle to present, open, and release individual clamps
Inventor: LUTZE THEODOR
IPC: A61B17/068
Filed: 1980-09-19
Abstract: The mechanism is intended for placing U-clamps in scalp tissue or the like during an operation. The clamps, each having two arms and an opening in its cross-bar, are contained in a magazine from which it can be moved by a pusher assembly with two spreader arms by depressing a spring-loaded handle. The spreader arms pass through the opening after which the clamp is pushed forward and then opened by the spreader. Releasing the handle retracts the assembly thus applying the spring clamp to the tissue. At the same time, the magazine rotates to present a further clamp for apolication.
